Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing these Jeep CJ, SB Chevy V8 engine swap specific header model for over 20 years. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

These BLACK-MAXX coated, LONG-TUBE headers are designed specifically for installing a Small Block Chevy 283-400 (Gen 1) engine into a 1976-1986 Jeep CJ5, CJ6 and CJ7. The smooth 1-5/8 in. tube design provides ample exhaust flow to let your CJ's transplanted 283-400 SB Chevy engine breathe easy, and produce maximum torque to power you through virtually any trail.

These headers were designed in conjunction with Trans-Dapt Performance Products' #4100 engine mount kit, and to avoid possible header installation issues, it is recommended that the headers be ihnstalled with the Trans-Dapt #4100 engine mounts.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.

Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. These headers have a high temperature, SATIN-BLACK ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5-year factory warranty, in addition to Hedman's standard lifetime header warranty.
